NUMBERIN'G-MAGHINE.

resents.

To (ZZZ whom it may concern Be it known that we, WILLARD W. Sawrne andEmit H. JUNGK, citizens of the United States, and residents of Brooklyn,in the county of Kings and State of New York, have invented certain newand useful ltm n'ovements in Numbering-Hachines, of which the followingis a specification.

This invention relates to numbering machines, and is particularlyapplicable to machines known as typographic or printers machines to belocked up in forms with type, and to be operated by a printing press.

@ne of the objects of this invention is to produce a numbering machinearranged so that the numbering wheels and the pawls for operating thesame may be readily removed from the machine for cleaning purposes, andoccasionally, for the substitution of one wheel for another, withoutdismantling the whole machine or disarrang ing the wheels.

Another object of the invention is to pro vide a simple form ofmechanism for operatingt-he pawl swing.

With these and other objects in view, our invention consists of certainnovel features of construction, combination and arrange ment of parts aswill be more fully de scribed and pointed out in the appended claims.

In the drawing, Figure 1 represents a plan view of our typographicnumbering machine in the form which we have chosen for purposes ofillustration. Fig. 2 is a side elevation of Fig. 1 looking from the leftof Fig. 1. 3 is a section on the line 3-3 of Fig. 1 looking from theleft of Fig. 1. Fig. 1 is a side elevation of Fig. 1 with the bearingcovering cap thrown down to more clearly show the mechanism, and Fig. 5is a section on the line 5-5 of Fig. 4.

The corresponding parts are referred to both in the drawings andspecification by similar reference characters.

111 the drawings, is a frame, hollowed out as shown to provide a recessin which may be mounted the usual numbering wheels 11. This frame 10 isprovided with slots, as shown particularly in Fi 2, in which may beinserted the flattened ends 12, 13 of a shaft 14- on which the numberingwheels 11 are mounted. On this shaft ll is also mounted a pawl swing 15carrying the usual pawls 16. The pawl swing moves Specification ofLetters Eatent.

back and forth in the usual manner to operate the numbering wheels, allas will be understood by those skilled in the art. Detent pawls 16 areprovided for each of. the numbering wheels, held in place by the usualsprings 17, the unit numbering wheel being controlled by the pawl 18.The shaft 141 is held in place in the slots in the frame 10 by aremovable cap 19 which, in the form we have illustrated, is hinged at 20to the frame 10, and is held in closed position by a fastening device20. This cap 19 preferably formed so that, when in place, it becomes acontinuation of the frame 10 to add strength thereto, as well as to holdthe shaft 14: in position.

Slidably mounted in the frame 10 is a plunger 21, of the usual type,which is held in its upward position by the pressure of a spring 22extending into a recess 28 in the frame 10. The plunger 21 is providedwith an over-hanging projection 24. which is provided with a slot, asshown particularly in Fig. 3, spanning the shaft 1 1-. Preferably theaws of this slot are so arranged that when the plunger 21 is pusheddownward until the top thereof is level with the printing surface of thetype of the wheels 11, the upper wall of the slot contacts with theshaft 1 1 to provide a limiting stop for the plunger. Likewise when thepressure is removed from the plunger 21, the spring 22 forces theplunger upward until the lower wall of the slot in the ovenhangingprojection contacts with the bottom of the shaft 1 1 to provide a stop.

C-n one end of the pawl swing 15 we pro vide a projection arranged toengage with the walls of the slot in the projection 2 1, so that thevertical movement of the plunger 21 will be converted into a rotaryoscillating movement of the pawl swing 15. its a convenient form formanufacturing purposes, we construct this projecting member of the steelblocks or pins 25 riveted into the end of the pawl swing 15, although,of course, it will be understood that any other form of construction maybe used.

The shaft 14 will usually be provided with a longitudinal groove tocooperate with a drop cipher construction of the usual type, such as isillustrated in the patent to l l icht No. 391,289, which groove, as willbe understood by those skilled in the art, must be 3,,

held in definite position in relation to the frame 10 in order that thedrop cipher will operate at the proper time. It is, therefore, desirablethat in placing the shaft 14; with the wheels thereon in the frame 10,means shall be provided by which it will be assured that the shaft canbe entered in its place only when this groove is in proper relation withthe frame. To this end, and as a convenient means for accomplishing thispurpose, we cut the slot for the end 13 of the shaft 14, so that itintersects the socket 23 in which the spring 22 operates, and shape theend 13 so that it can be entered into the slot in the frame 10 only whenthe longitudinal groove in the shaft is in proper relation to the frame10. As will be seen more clearly by an inspection of Fig. 5, the end 13is cut away to permit the admission of the end 13 into its groove whenthe parts are in the position shown inv Fig. 5, or to prevent suchentrance if the shaft is turned over, as the longer portion of the end13 cannot pass the spring 22.

As will be seen by an inspection of Fig. at, the removal of thefastening device 20 permits the cap 19 to be swung downward on its hinge20, so that the shaft 14:, carrying the wheels and pawl swing, may beremoved bodily sidewise from the frame 10 without disturbing therelation of the numbering wheels or the pawl swing. This provides aneasy and ready method by which the wheels may be removed for cleaningpurposes and for returning them to their position without disturbingtheir relation. The shaft 14 also serves as a lock to hold the plunger21 in the frame 10 when the shaft is in place.

It will be understood that many other forms may be used in place of ourswing cap 19. For instance, separate bearings might be provided over theends 12, 13 respectively, and these hearings may be removable bodilyfrom the frame 10 instead of being hinged thereto, although we preferthe latter form, since by this means the cap is always connected to theframe and in no danger of being misplaced.

Having now described our invention, what we claim as new and desire tosecure by Letters Patent is as follows:
